Dazzled paintings are paintings on ships to confuse the enemy.
During WWI they were used a lot, but even in WWII they were used.
Normam Wilkinson gets the credits for these complex paintings to artist Norman Wilkinson, consisting of a pattern of geometric shapes in contrasting colours, interrupting and intersecting each other.
Because of the paintings it is hard for the enemy to see how far away a ship is, of which directions it is sailing.
There is a discussion these days; some people do not believe the paintings do their work. (more info)
